[PLASMA CUTTER ] PEMOTONGAN PLAT TEBAL MENGGUNAKAN MESIN PLASMA CUTTER

Summary

In this video, the presenter demonstrates cutting a 17mm thick steel plate using a plasma cutter, sharing their first experience with this process. Although the presenter typically uses acetylene for cutting, they opted for plasma due to the thick paint on the plate, which could cause issues with traditional methods. The presenter explains how the plasma cutter worked efficiently, resulting in clean cuts and a smooth finish. They emphasize the importance of proper machine setup and preparation, and express satisfaction with the plasma cutter’s performance for thick materials.

Takeaways

• 😀 The video demonstrates cutting a 17mm thick steel plate using a plasma cutter, a process the presenter had never done before.
• 😀 The presenter emphasizes the importance of adjusting the plasma cutter's settings to ensure smooth and precise cuts.
• 😀 The plate used in the demonstration was 300x190mm, but a 16mm plate was initially requested. The presenter uses a 17mm plate instead, explaining it's close enough.
• 😀 The plasma cutter used in the video is a BP 92 model, with an amperage set to around 90A to ensure effective cutting.
• 😀 Before cutting, the presenter checks the plasma cutter's indicator lights. A red or yellow light means the cutter won't work correctly.
• 😀 The presenter highlights that while using a manual cutter works for thinner plates, a guiding tool is necessary for precise cuts on thicker plates like the one shown.
• 😀 Testing and setting up the plasma cutter before starting the cut is crucial for achieving the best results.
• 😀 The presenter mentions that using acetylene or a blender for cutting would have been dangerous due to the thick paint on the plate, which could explode under those conditions.
• 😀 The plasma cutter proved to be highly effective, yielding clean cuts without any major issues, which surprised the presenter.
• 😀 After cutting, the slag or debris on the plate's edges was easily removed by tapping it with a hammer, leaving a clean surface.
• 😀 The presenter encourages viewers to try using a plasma cutter for cutting thick plates, noting its reliability and effectiveness.

Q & A

Why did the presenter choose a 17mm thick plate instead of a 16mm plate?

The presenter initially wanted a 16mm plate, but they couldn't find one, so they opted for a 17mm plate, which is still acceptable since it's slightly thicker than the required 16mm.

What equipment is being used for cutting the metal plate?

The presenter is using a BP 92 plasma cutter, which is set to an amperage of around 90 for cutting the 17mm thick metal plate.

How does the presenter ensure that the plasma cutter is ready to use?

The presenter checks the plasma cutter’s indicator light. A blue or green light indicates that it is ready to use, while a red or yellow light means there may be an issue, such as insufficient air pressure.

Why does the presenter use a guiding tool for the cut?

The presenter uses a guiding tool to ensure precision when cutting the thick plate, as manual cutting could be less accurate for such a thick material.

What is the main reason the presenter switches to plasma cutting instead of using an acetylene torch?

The presenter switches to plasma cutting because the plate has a thick coating of paint. Using an acetylene torch could cause the paint to explode, which is why the plasma cutter is chosen for its cleaner cut.

How did the presenter feel about the performance of the plasma cutter on a thick plate?

The presenter was pleasantly surprised by the performance of the plasma cutter, as it worked effectively on the 17mm thick plate, something they had never tried before.

What precaution does the presenter take before starting the cutting process?

Before starting the cut, the presenter tests the equipment settings to ensure that the plasma cutter is functioning properly and that the cut will be precise.

What was the challenge the presenter faced with using acetylene for this job?

The challenge with using acetylene was the thick paint on the plate, which could cause dangerous explosions if not properly dealt with, making the plasma cutter a safer choice.

How does the presenter describe the cutting process after testing the equipment?

The presenter describes the cutting process as smooth and easy, mentioning that the plasma cutter worked very well on the thick plate, and the results were better than expected.

What steps does the presenter take to finish the cutting process after the plasma cutter does its job?

After cutting, the presenter taps the slag off the edges of the plate to remove the unwanted residue and ensure a clean finish.
